The angle valve won't fit inside the cowling. Sorry. I guess you could make a new cowling, but it'd be a helluva lot easier to use a parallel valve and just put in a baggage compartment, or inverted oil system, or lead brick, or a flywheel weight, or just use a constant speed prop.

No offense to Catto's very fine products intended!!! Hmmm, if only they started making CS props too... yeah, that's the ticket!

They are building constant speed props. Very few though. They are also going through the process for FAA certification. When both of those go into full swing, look out. I just spent 10 days there doing an “internship” (building my other project).

Btw, would love to build an F4.

The information that I post is just that; information and my own personal experiences. You need to weight out the pros and cons and make up your own mind/decisions. The pictures posted may not show the final stage or configuration. Build at your own risk.
